A design team led by architects Allies and Morrison and Asif Khan Studio will deliver a multi-million pound revamp of the Barbican Centre.
Chosen from a short list of five, the winning team includes engineering and sustainability consultants, artistic advisors and heritage experts.
Their vision for the Grade-II listed building will now be developed against a budget of £50m to £150m, subject to approval from City Corporation members.
Plans to refurbish the Barbican were first floated last year after the City Corporation axed proposals for a £288m Centre for Music.
Simon Fraser, Partner at Allies and Morrison, said the Barbican's re-design will look to untap potential around the centre and reduce the carbon footprint of the building.
“[It will] respect the Centre’s significant heritage value, [and] open a myriad of opportunities for creative, inclusive reinvention.”
